So the fix is just a computer reflash to power down the engine in the case of a leaky injector dumping more fuel into the exhaust.
That's what I thought, it's just a safety bandaid deal.

Wow - that flame video is just amazing to watch... unbelievable. 
I take it that the extra injector responsible for heating the DPF when it's in regen mode is leaking?
Very dangerous, IMO!
I hope Dodge procures the new urea-based emissions system from MB for the next model year, or ASAP - from an engineering standpoint, it seems as though it's a simpler, more efficient and inherently safer design than the current DPF interim solution.

No, it's one of the cylinder injectors. If it wasn't in regen mode then you'd just see some white smoke instead of 2 foot flames.

Man Dave's always got the answer. Thats why I like that guy even tough I have got in trouble a few times. I didn't think it would have an extra injector, but didn't know if it used 1 or 8 to raise the temps. the 07 dodge 5.9 dose the same thing to clean out the DPF. Fords plob is all because of a leak not in the design itself.

The Cummins Heavy Duty ISM and ISX uses a aftertreatment injector for hydrocarbon injections. the ISB uses a very late post injection during the exhaust stroke for oxidation heat in the aftertreatment. The use of Urea is coming , but you will still have the DPF, Urea is only for reduction of the NOx output from the engine. you still have to trap the PM from the engine. Urea will not reduce the PM.

You may be right but that would seem like a step backwards in technology. Everybody making big deal about the new piezo electric injectors and all,and for them to not use the system to it's full capabilty seems so...like something FORD would do. So you probably are right!

Actually driven my B-I-L's new E series bluetec powered sedan.. WOW! LOTSA power!
We could see an extra fuel line headed back towards the turbo exhaust area. (couldn't see much beyond that).
